|CMS jobs unavailable Weds 27th September|

An upgrade to the CMS@Home workflow management system (WMAgent) is planned for tomorrow (Wed Sep 27th). This needs the current batch of jobs to be stopped so that the queue is empty. I plan to do this about 0700-0800 UTC on Wednesday.
To avoid "error while computing" task failures and the resulting back-off of your daily quotas, we suggest you set all your CMS machines to No New Tasks at least 12 hours beforehand to allow current tasks to time out in the normal way. You can stop BOINC once all your tasks are finished, if you wish.
Exactly how long the intervention will take is unclear, and there will be a delay of up to an hour to get a new batch of jobs queued afterwards. I will post here when jobs are available again, hopefully before the end of the day European time.
|Collatz: Search finished|
samedi 23 septembre 2017 00:00
After less than one and a half months (14 August to 23 September), we were able to successfully complete our search project: We have found all the smaller path records as well as all starting numbers 2 * 1016 * starting number (only such numbers are given as candidates) which were found by other persons (mainly Tomas Olivera e Silva and Eric Roosendaal); and thus validate our approach in the opposite direction. We have found 4 new path records and have been able to prove that all starting numbers

A group of BOINC developers, project managers, researchers, and volunteers recently participated in a workshop where they exchanged information and ideas that will help set the direction for the future development of the BOINC open source project.

I've been asked by several people to post a status update on the situation at Arecibo following hurricane Maria's passage.
Unfortunately, at this point we haven't gotten any news. The last information we have is from a couple hours prior to when the eye passed Arecibo. That report said all the employees were accounted for and in sheltered buildings.
Since then we've had no news. That's understandable. With power out on the whole island, electronics communications aren't going to be possible for some time. Heavy rains are still expected today, so I'm sure that the primary concern is still keeping everyone safe. Assessment of any damage will take time.
Let's hope that everyone is safe, that their homes are intact, and that any damage can be repaired quickly.

|Possible systems failures|

We seem to be in the early stages of a system failure for several sub-projects. The proxy server has flatlined and my running jobs monitor is dipping alarmingly. Please check if you are getting tasks flagged as computing failures, and set No New Tasks if so.
[Edit] On closer inspection, it may just be the CMS app. [/Edit]
Obviously I'll apologise if this is a false alarm, but it's the wrong time of day to expect a prompt response from the CERN admins.
|Bad Runs Over the Weekend|
lundi 18 septembre 2017 16:07
Sorry about the errors over the weekend. I put up a set of runs that, while tested locally, still seemed to error on the server. The runs are now taken down and should filter out of the queue over the next 24 hours, going to look into it now.

A new feature has been implemented to shutdown multicore VMs at the end of their life when the idle time > busy time. This means that if we are wasting more time with empty cores than we would loose by kill the remaining jobs, those jobs are killed. This should avoid the situation where a looping Theory job keeps the VM alive while wasting idle cores. If this works the following message should be seen in the task output.
Multicore Shutdown: Idle > Busy ( 1439s > 1382s )
Let me know how it goes.
|Data from "Tabby's Star" is flowing.|
jeudi 7 septembre 2017 18:36
For those who didn't recognize the name KIC8462852 in their work unit names, this data comes from GBT observations of Tabby's Star (aka Boyajian's Star, aka WTF-0001, aka the Weirdest star in the galaxy). This is not yet the full data set, which lives at Penn State, it's some test on-target/off-target observations that we're checking out.
You might also notice another change. We've doubled the size of our work units which will reduce our quantization noise by 34%, and, depending on the strength of other noise sources, could give us as much as double that as a sensitivity increase.
